BACKGROUND

The present invention related to exercise apparatus and moreparticularly to a new apparatus having a horizontally oriented rotatablecylinder and elongated side handles to enable the user to exercise onand across the cylinder in a variety of new exercise positions,extensions, orientations, and methods.

Children have flexible back muscle that allow them to arch with theirchest upward with ease. As adults, without Exercising gravity pulls thebackbones downward which causes compression and stiffness in theseareas. Most back pain is due to pressure on a disc and/or irritation ofthe ligaments and muscles around disc. Pressure on a disc can result inpressure on a nerve or nerves of the spine which can also cause backpain. Due to ago, injury, or unhealthy occupation or lifestyle, it isnecessary to build and exercise equipment to stretch and strengthen theback muscles, stretch the ligaments, and strengthen the intervertebraldisk and nerves.

Placing the lumbar spine in a passively extended position allows thestrained structures to come closer together, and in response, becomestronger and thicker. To accomplish this, the spine should be stretched:forwardly, backwardly, and sidewardly, to increase flexibility and tostrengthen and condition ligaments and other connective tissues whichhold the vertebrae together. Strengthening and stretching the backmuscles provides stability around the muscle and ligaments to betterhold the vertebrae in place.

Various machine have been designed to address the above-mentioned backproblems, see for example U.S. Pat. Nos. 1,643,039; 6,478,721;6,245,000; 5,634,887; 5,242,342; 6,375,601; 2,048,587 and 195,247(1877).

Many attempts have been made to address the attractive appearance andhealth issue of flattening the abdomen or stomach by stretching andstrengthening the abdomen. There has always been a desire to focus on aeconomic and fast way to lose fat around a person's mid-section. Forexample, abdominal exercise device of U.S. Pat. No. 1,936,022 has amounted motor inside a casing allows for vibration of a ball on theabdominal area. It does not fully work the abs and the device can beuncomfortable and tedious, with little of no effective results inabdominal muscle strengthening.

SUMMARY OF EXEMPLARY EMBODIMENT OF PRESENT INVENTION

The apparatus according to the principle of the present inventionincludes a cylinder mounted for horizontal axial rotation on a frame anda pair of elongated side handles extending from behind and below thecylinder upward and forward to substantially above the cylinder. Thisfundamental arrangement enables the user to address the cylinder eitherby facing the cylinder or facing away from the cylinder either by facingthe cylinder or facing away from the cylinder, grasping both sidehandles from the undersides and pulling and/or pushing the user's bodyback and/or torso across the cylinder to rotate the same. In this way,user not only strengthens one's arms and upper body, but the normalweight of ones upper and lower body parts are efficiently used tostretch the parts directly supported by the cylinder. In addition, usercan continue this action or remain stationary on the cylinder whilewalking user's hands from the upper side handle portions down to thelower side handle portions to extend and stretch the back and/or abdomenmuscles in a new and controlled manner. As user's hands graspincrementally lower party of the handrails, the body is flexed andstretched incrementally more. To withdraw user need only walk users handupward on the side rails to rise to a position enabling user to dismountthe apparatus.

Additional features of the exemplary embodiment include verticaladjustment of the cylinder height to accommodate various user heights(including children). For and aft extending bottom handles for handand/or foot gripping or standing. These bottom handles preferably extendfore and aft of the vertical frame members supporting the cylinder axle.

Advantageously, the exemplary embodiment according to the principles ofthe present invention provides a number of new exercise options to user,some of which shall be described below.

A principal object of the present invention is to provide an apparatusthat more effectively exercises the user's spinal system, abdominalsystem, and other muscular and circulatory systems than prior knowapparatus.

SUMMARY OF INVENTION

With reference to FIGS. 1-6, one exemplary exercise apparatus 10according to the principle of the present invention includes a bottomfree assembly 12 having a pair of bottom side rails 14 rigidly connectedin spaced, preferably parallel, arrangement by cross strut 16. Althoughonly one strut 16 is shown, two fore and aft spaced struts can beemployed as desired.

Apparatus 10 further includes upstanding post assemblies 16 secured onthe forward portions of rails 14. Each post assembly 16 includes avertical series of horizontally aligned through-holes 18 for receivingand mounting cylinder axel 20, better seen in FIG. 2.

Apparatus 10 further includes a pair of arcuate or angled handrailassemblies 22, which preferably include a rear arcuate handgrip sections24 with its rear end mounted to the rear portion of rail 14 and upperend joined to hand grip section 24, which are preferably horizontallyoriented. Sections 26 are joined to upstanding sections 28 which, inturn, are supported by post assemblies 16. Frame assemblies 12, postassemblies 16 and hand rail assemblies 22 should be made of metal orother suitable material that can support maximum user weight plus asuitable safety factor. Shapes and cross section shapes of theseassemblies can be any suitable design such as box cylinder, tubular,triangular, or other. In this example handrails 22 are tubular withtheir forward, lower ends 28 inserted within the square tubes of posts16 and secured therein by conventional fasteners 30. Although hand rails22 can be bare metal or heavy plastic, it is preferred that sections 24,26, 30 be covered or coated with softer foam or other material forproviding more hand comfort to users during operation.

Apparatus 10 further includes a pair of lower handrails 32 mountedbetween lower parts of handrail section 24 and posts 16. Lower handrails32 should be foam covered and also serve to help stabilize handrails 22and posts 16. Lower forward rails 34 have aft ends mounted to posts 16and forward ends vertically oriented to be mounted on the forward partsof frame rails 14. Lower rails 32 and rails 34 are preferably alignedfore and aft to further stabilize pasts 16 and provide hand and footgrips further described below.

Apparatus 10 further includes a cylinder or roller-assembly 36 having anouter preferably cylindrical surfaces 38 covered by a one or more layers40 of foam rubber or other suitable material for providing a cushion tothe user during operation. Cylinder 36 should be made of suitablematerial such as metal and have closed ends 43 having a central openingand bushing 44 to accommodate threaded axel 20. Axel 20 inserts throughlock washer 46, and post 16, disks 42, bushings 44, the other post 16,lock washer 48 and threads into wind nut 50. Accordingly, cylinder 36can be selectively assembled for rotation at any desired verticalposition determined by the selected opening 18 through which axel 20passes.

It will be appreciated by those of ordinary skill in the art thatfurther positions and static and dynamic exercises can be implemented onapparatus 10 and that the above mentioned exercise methods are examplesand not the methods possible.

Although the soft cylinder cover 40 is shown as having a substantiallycylindrical surface, if desired, cover 40 could have a horizontal ribbedsurface (FIG. 5) or a circumferentially ribbed surface (FIG. 6). Otherdesigns are possible as desired.

An alternate arrangement for cylinder and post support can be seen inFIGS. 8-10 in which cylinder assembly 36A includes a central axel 20Ahaving a bushing or bearing assembly 45 mounted on each end of axel 20A.Each port 16A includes a support channel 17 facing cylinder 36A. Aseries of vertically spaced support rods 47 are seated throughrespective and aligned holes in the fore and aft channel parts. Rods 47are releasably held in channel 17 by spring biased snap buttons 19. Toinstall cylinder 36A, a predetermined rod 47 is inserted though eachrespective holes in each channel 17. Each brushing or bearing assembly45 is inserted into the open top of each channel 17 and assembly 36A islowered until the bearings 45 rests on rods 47. Then, a second pair ofrods 47 is installed though the openings just above the bearings 45 tocomplete the installation.

To adjust the vertical position of cylinder 36A, rods 47 above bearings45 are removed to allow upward adjustment or below bearings 45 to allowdownward adjustment of cylinder 36A. The removed rods 47 (or other sparerods 47) can be installed below or above the new (desired) position andcylinder 36A moved to that position and held manually while theremaining rods 47 are installed to secure the vertical position asdescribed above.

Yet a further exemplary arrangement is shown in FIGS. 10, 11 in whichcylinder assembly 36B includes central axel 20B which is preferablythreaded at both ends to cooperate with respective wing nuts. Bearingassemblies 45B are bounded by spacers or washers 49. Posts 16B include avertical series of forward opening slots 51 that extend rearward anddownward generally as shown. Alternately, slots 51 could open to therear and could have other shapes, such as simply horizontal. Also,cylinder assembly 36B could have an axel with but a single threaded axelat one end with an enlargement at the other end, if desired.

To install, initially washers 49 are slide onto axel 20B to contactbearings 45B. Assembly 36B is then inserted into the selected verticalposition by sliding axel 2B through respective horizontally alignedslots 51 and seated therein. Next lock washers can be installed outsideposts 16B and then wing nuts threaded on both ends tightened againstlock washers and posts 16B to secure the position. Note the full weightof the cylinder and user is carried by posts 16B. Wing nuts serve toclamp the assembly to prevent axel 20B from moving toward the slot 51opening.

To change cylinder 36B vertical position on apparatus 10, wing nuts areloosened but not removed from axel 20B threaded ends. This removes theclamping actions mentioned above. Axel 20B can now be lifted and movedfree from slot 51 through the openings thereof. User simply movescylinder 36B to the new vertical position, inserts and seats axel 20Binto the respective new slots 51, and tighten wing nuts to complete theadjustment.

Other functions changes and improvements can be made to the exemplaryembodiments disclosed herein without departing from the spirit and scopeof the present invention.
